Fluid Component Engineer II

ABOUT ROCKET LAB Rocket Lab is an end-to-end space company delivering responsive launch services, complete spacecraft design and manufacturing, payloads, satellite components, and more – all with the goal of opening access to space. The rockets and satellites we build and launch enable some of the most ambitious and vital space missions globally, supporting scientific exploration, Earth observation and missions to combat climate change, national security, and exciting new technology demonstrations. Our Electron rocket has become the second most frequently launched U.S. rocket annually and has delivered more than 230 satellites to orbit, all while we work to develop Neutron, our upcoming medium-lift, reusable launch vehicle for larger constellation deployment. Our Space Systems business designs and builds our extensive line of satellites, payloads, and their components, including spacecraft that have been selected to support NASA missions to the Moon and Mars and components used on the James Webb Space Telescope. NEUTRON ROCKET Neutron is a medium lift launch vehicle capable of delivering the mega constellations of tomorrow, high assurance payloads, and human spaceflight. As a highly reusable launch platform, Neutron will deliver a highly cost-effective and reliable launch solution leveraging Rocket Lab’s proven execution history with the Electron program. FLUID COMPONENT ENGINEER II The Fluid Component Engineer II plays a key role in the design, build and test of fluid components across the Neutron launch vehicle, including valves, actuators and regulators. You will collaborate with an amazing team of engineers in the Fluid Systems department to turn vehicle-level requirements into a family of fluid components that enable Neutron to operate with aircraft-like reusability and reliability. WHAT YOU’LL GET TO DO Own fluid component designs from concept through launch Create and maintain analytical models to size new components from first principles and predict sealing, force balance, structural and timing behavior Create and maintain component product definition through CAD models, technical drawings, and test procedures Lead key component design, manufacturing and test reviews Manage vendor and internal schedules during design, build and test sprints. Build and test prototype components hands-on, collaborating with machinists, build technicians, manufacturing engineers, and test engineers Lead test campaigns to qualify components for flight Conduct root cause failure investigations of hardware, and implement design fixes to achieve reliability Update existing component designs to address critical failure modes while reducing cost and mass and increasing build rate . Review data from engine and vehicle test operations to validate component performance and diagnose anomalies YOU’LL BRING THESE QUALIFICATIONS Bachelor’s degree in mechanical engineering or aerospace engineering 2+ years of experience with mechanical design and assembly, CAD, Finite Element Analysis (FEA), 2D drawings, geometric dimensioning and tolerancing (GD&T) Strong first-principles engineering knowledge to establish and challenge requirements and develop optimized designs Knowledge of metal and polymer material properties, fabrication, fastening, assembly and testing methods Strong engineering fundamentals in structural analysis, fluid dynamics, thermodynamics and electromechanical systems Demonstrated ability to bring definition to complex design problems in a fast-paced environment with information available Hands-on experience with prototyping, mechanical assembly and pressure testing THESE QUALIFICATIONS WOULD BE NICE TO HAVE 5+ years experience of aerospace valve specific design, build and test Experience with cryogenic oxygen & methane components and combustion devices Experience using fluids analysis tools such as REFPROP and GFSSP Experience using Siemens NX Experience using Python Experience with precision CNC machining (mill and lathe) and CAM This p…
